Customer Reviews
The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

ULTRASONIC TECHNOLOGY FROM NATURE TO INDUSTRY
Latest company news about ULTRASONIC TECHNOLOGY FROM NATURE TO INDUSTRY

Ultrasound has always been a part of mother natures solutions. Bats use it in particular to orient themselves and to fly. By emitting brief ultrasound pulses of less than 1/1000 s duration at a frequency of 50,000 Hertz, they can locate obstacles, but also find the insects on which they feed. Dolphins and blue whales are also able to navigate using acoustic signals. They use a frequency of 170,000 Hertz audible only to their inner ear.

 

At the beginning of the sixties, the transformation of synthetic materials experienced a real boom. In fact, for the assembly of synthetic components, and with an understanding of the natural acoustic phenomenon, the ultrasound welder was developed and had a predominant role.

 

In the industrial field, SONIMAT began using very early on ultrasound for assembly, welding, cutting and slicing applications. Other professionals have also discovered the advantages of this technology:

Medicine : mainly for ultrasound and focused ultrasound thermotherapy.

Laboratory : sonication breaks down cell membranes. Ultrasound is also used to clean and disinfect equipment.

Remote sensing and telemetry : sonar and distance measurement.

Automotive : ultrasonic parking assistance system and obstacle avoidance.

Industry : non-destructive testing of materials.

Leisure and practical life : pest control devices, atomiser.

Hairdressing : implants for hair extensions.

 

 

APPLICATIONS OF ULTRASONIC WELDING TECHNOLOGY

Ultrasonic welding

Assembly by energy applicator. Mainly reserved for amorphous thermoplastics. Ultrasound welding is done very quickly (less than 1 second), without adding material.

 

Ultrasonic spot welding

Ultrasound spot welding is particularly recommended for thermoformed parts without an assembly profile, or for parts whose geometry and actual conditions exclude the possibility of standard welding operations.

 

Continuous ultrasonic welding

Applied to high speed processes, continuous ultrasound welding is a solution for the high flow rates in the fields of packaging and non-woven textiles.

 

Ultrasonic riveting assembly

The main advantage of this process is that it allows to assemble parts of different types of plastic.

 

Flanging

This technique encloses a part within a completely different material, by deformation of the material.

 

Insertion

The penetration of metal inserts by ultrasound makes it possible to avoid the stresses due to overmoulding, to increase the injection rates and to simplify the production of injection moulds.
